To transfer a concentrated acid, a reactive chemical mixture, or a fluid intended for a process pharmaceutical, the industrial pumps<\/strong> They must be designed to maintain reliable and safe performance even when they come into contact with hazardous substances or high temperatures.<\/p>\n A standard centrifugal pump may not be suitable for every requirement: the chemical compatibility of the components, the resistance of the contact surfaces, the sealing system, the flow rate demand and pressure conditions must be evaluated together, taking into account the active behavior of the fluid. It is at this stage that the Customized industrial pumps<\/strong> they offer more appropriate responses than a configuration chosen solely based on general parameters.<\/p>\n Among the solutions to be taken into account most prominently are centrifugal pumps with a coating of PFA<\/strong>, a fluoropolymer characterized by high chemical resistance, good thermal stability, and particularly interesting properties for handling aggressive fluids and applications that require high levels of purity.<\/p>\n CDR Pompe<\/a> It provides design, customization, and technical support expertise, as well as a wide range of PFA-coated products designed for the handling of chemical and pharmaceutical fluids.<\/p>\n Customized industrial pumps adapt to the characteristics of the work to be performed. A fluid can be compatible with a specific material at a certain temperature and result more aggressive in different conditions; similarly, a pump properly sized from a hydraulic point of view must be constructed with materials and components suitable for the environment in which it will operate.<\/p>\n Before identifying the most suitable configuration, it is therefore necessary to collect and evaluate a series of technical information. The parameters to be considered include:<\/p>\n PFA, or perfluoroalkoxy, belongs to the family of fluoropolymers and is now used in a wide range of sectors thanks especially to its high chemical inertia. As for centrifugal pumps, its use as a coating allows for the protection of surfaces exposed to corrosion, offering a barrier against numerous aggressive agents.<\/p>\n The PFA\u2019s choice is linked to a set of properties that are very useful in handling industrial fluids. Among the main characteristics:<\/p>\n These characteristics make the PFA a solution to be considered in the design of industrial pumps<\/strong> Customized<\/strong> designed for chemical plants, environments in which contamination of liquids must be prevented and a very high standard of environmental safety must be guaranteed.<\/p>\n One of the main reasons why PFA is considered in chemical applications is its resistance to many aggressive fluids. The coating can be particularly interesting when the pump surfaces are exposed to substances capable of attacking or deteriorating materials that have not been properly selected.<\/p>\n Among the fluids for which the use of PFA-coated centrifugal pumps can be considered are:<\/p>\n The list should not be interpreted as an automatic compatibility with any concentration or temperature. The selection of the industrial pumps<\/strong> It must always start from the fluid data and the process conditions, verifying that the PFA and the other materials used are suitable for the intended application.<\/p>\n When a pump operates with corrosive fluids, material deterioration is the main danger. Chemical attack can indeed affect the contact surfaces, altering the characteristics of the components and making more frequent maintenance necessary. Choosing an appropriate coating reduces this risk, protecting the exposed parts within the limits specified in the technical specifications.<\/p>\n The PFA in particular, thanks to its characteristics, can offer an important contribution to the lifespan of industrial pumps.<\/strong> Of course, the lifespan of a pump also depends on other factors such as proper sizing, operating conditions, installation quality, and maintenance performed. The coating alone does not eliminate wear or replace proper technical management.<\/p>\n However, when the pump is properly designed, equipped, and installed, the data show a reduction in extraordinary maintenance interventions on the systems (with a clear reduction in management costs) and a significant increase in the pump\u2019s lifespan. Furthermore, such protection against corrosive agents maintains production continuity, simplifying the planning of the entire activity as well.<\/p>\n For those who need to purchase and manage industrial pumps in a plant chemical<\/a>, Evaluating the resistance of materials therefore means considering the consequences of the choice on the environment. maintenance and continuity of service.<\/strong><\/p>\n The protection of operators and the working environment is linked to the pump\u2019s ability to contain the fluid. In this sense, the PFA coating can be combined with a configuration with magnetic drive<\/strong>, In which rotation transmission occurs through magnetic coupling, without the direct mechanical connection typical of pumps equipped with mechanical seal<\/a> traditional.<\/p>\n The PFA and the magnetic drive interveners thus address two different aspects of the pump: the first concerns the chemical resistance of the surfaces in contact, while the second concerns the fluid containment system.<\/p>\n The integration of these features, resistance to corrosion and reduced risk of dispersion of the liquid being transported, guarantees a high level of protection for both workers in contact with the pump and the environment, and also allows the company to comply with all the strict regulatory requirements typical of the chemical, pharmaceutical and food sectors.<\/p>\n For this reason, in industrial pumps<\/strong> For fluids classified as hazardous, the assessment of the coating must be accompanied by an analysis of the sealing or containment system and of the overall operating conditions.<\/p>\n The regulations in force in sector pharmaceutical<\/a> They require some of the highest hygienic and sanitary standards in the world.<\/p>\n PFA also has interesting characteristics regarding cleanliness, thanks to its chemical inertness, smooth, non-porous surface, and its tendency not to retain residues. These aspects contribute to the handling of fluids of high purity.<\/p>\n Among the elements to be considered in choosing industrial pumps<\/strong> Customized for the sector pharmaceutical:<\/p>\n It is important to clarify that the presence of a PFA coating does not automatically determine the compliance of the entire pump with every requirement pharmaceutical. Materials, finishes, design, documentation, cleaning procedures, and applicable regulations must be verified based on the specific application.<\/p>\n There is no material that can be considered the best choice for every fluid and every application. Comparison with other construction solutions, including those in metallic materials or with other fluoropolymers<\/a>, As always, you must take into account all the parameters we have discussed.<\/p>\n In general, the PFA can be considered as the cladding of a industrial customized pump when a request for customization is made. high resistance to corrosion<\/strong>, Because of very aggressive substances, and when the tExercise temperatures are significantly high<\/strong> and a certain threshold of thermal stability must be maintained.<\/p>\n The PFA is also suitable for continuous and long-term processes<\/strong> and to mobilize the liquid that must be maintaining unchanged concentration and purity<\/strong>. This is a coating that guarantees enormous reliability in chemical applications, while maintaining the pump\u2019s performance under the intended operating conditions.<\/p>\n Centrifugal pumps with PFA coating<\/a> They can be used in various applications: the applications can vary depending on the fluid, the concentration, the temperature and the performance requirements of the system.<\/p>\n In the sector chemical, the industrial pumps<\/strong> Custom-made PFA-coated containers can be evaluated for handling aggressive substances in operations such as:<\/p>\n In the sector pharmaceutical, attention is also focused on product quality and the cleanliness of equipment. Among the applications to consider are:<\/p>\n The PFA coating, also used for CDR centrifugal pumps<\/strong>, It offers significant advantages thanks to its resistance to numerous chemical agents, thermal stability, and surface characteristics that simplify maintenance and cleaning.<\/p>\n For companies that use industrial pumps<\/strong> In chemical pharmaceutical these sectors, a PFA coating combined with an appropriate configuration, such as the magnetic drive<\/a>, contributes to the safe management of the fluids being handled.<\/p>\n CDR Pompe It assists its customers in the selection and customization of centrifugal pumps intended for industrial processes, providing technical expertise, support in material evaluation, installation, and commissioning.\u2019After-sales service.<\/a><\/p>\nCustomized industrial pumps: what is important to consider<\/h2>\n
